Is muscle atrophy serious?
What are the potential complications of muscle atrophy? Because muscle atrophy can be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage.
What is the greatest cause of muscle atrophy?
It’s usually caused by a lack of physical activity. When a disease or injury makes it difficult or impossible for you to move an arm or leg, the lack of mobility can result in muscle wasting.
How long do you live with SMA?

¿Qué es la atrofia fisiológica?
La atrofia fisiológica es causada por no usar los músculos lo suficiente. Este tipo de atrofia a menudo se puede revertir con ejercicio y una mejor nutrición.
